Description

Technical Field

[0001] This utility model relates to the field of aluminum-air battery production technology, specifically to an anode aluminum plate forming device for aluminum-air batteries. Background Technology

[0002] Aluminum-air batteries are a new type of battery that uses metallic aluminum as the negative electrode and air as the positive electrode. They have advantages such as high energy density, environmental friendliness, and low cost, and are widely used in energy storage and electric vehicles. As the core component of this battery, the forming quality of the anode aluminum plate directly affects the battery's performance and lifespan.

[0003] In the manufacturing process of aluminum anode plates, SLM (Selective Laser Melting) metal 3D printing technology can be used. This technology directly forms metal parts by melting metal powder with a laser. To improve the forming quality, the metal powder needs to be preheated in the powder supply box. This step can effectively improve the flowability and forming density of the powder, thereby ensuring the performance of the final product.

[0004] Patent CN222710819U discloses a preheating powder supply device for an SLM metal 3D printing equipment. The device includes a powder supply container for supplying metal powder to the printing equipment. The upper end of the container has a powder replenishment interface, and the lower end has a powder dispensing mechanism for supplying powder to the forming chamber of the printing equipment. An electrically heated heating rod is inserted into one side wall of the lower part of the container. A K-type thermocouple is installed inside the heating rod, with its heating end extending into the container. Both the heating rod and the K-type thermocouple are electrically connected to the control unit of the printing equipment, used to control the heating power of the heating rod based on the temperature obtained by the K-type thermocouple. Preheating the metal powder before powder spreading improves dehumidification, increases powder flowability, and allows for controllable heating, thus improving the efficiency and reliability of powder heating.

[0005] However, the anode aluminum plate forming device in the above technology still has the following problem: during the falling of metal powder, some powder slides off the sides of the heating rod, resulting in uneven heating. Specifically, the powder on the inner side contacts and is heated by the heating rod, while the powder on the outer side falls directly from the sides of the heating rod without effectively contacting it. This causes some powder to enter the forming stage without being fully heated, thus affecting the performance of the final product. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an anode aluminum plate forming device for aluminum-air batteries, which improves the preheating effect of metal powder at the powder supply box outlet.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anode aluminum plate forming device for aluminum-air batteries, comprising a powder outlet barrel, a heat-conducting pipe connected to the powder outlet at the bottom of the powder outlet barrel, the two ends of the heat-conducting pipe being connected to the two ends of the bottom opening of the powder outlet barrel respectively, an installation port being provided through one end of the powder outlet at the bottom of the powder outlet barrel, an electric heating rod being connected to the installation port, the electric heating rod passing through the installation port and being inserted directly into the heat-conducting pipe, and a heat-conducting component being connected to the outer wall of the heat-conducting pipe.

[0008] Furthermore, the heat-conducting component includes several heat-conducting pillars, all of which are fixed on the outside of the heat-conducting pipe, and the heat-conducting pillars are arranged in an equidistant, staggered pattern on the outside of the heat-conducting pipe.

[0009] Furthermore, a rotary drive motor is connected to the end of the heat pipe away from the electric heating rod. The rotary drive motor is fixedly installed on the outer wall of the powder outlet end at the bottom of the powder outlet barrel. The output shaft of the rotary drive motor passes through the powder outlet barrel and is connected to the end of the heat pipe. The end of the heat pipe away from the rotary drive motor is rotatably connected to the mounting port.

[0010] Furthermore, a heat insulation block is fixedly connected to the end of the heat pipe near the rotary drive motor. The output shaft of the rotary drive motor passes through the powder discharge barrel and is fixedly connected to the heat insulation block. A heat insulation pipe is fixedly connected and connected to the end of the heat pipe away from the rotary drive motor. The end of the heat insulation pipe away from the heat pipe is rotatably connected to the installation port.

[0011] Furthermore, an auxiliary bearing is embedded inside the mounting port, and the inner wall of the inner ring of the auxiliary bearing is fixedly connected to the outer wall of the end of the heat insulation tube away from the heat conduction tube.

[0012] Furthermore, an installation pipe is fixedly connected to the outer wall of the powder discharge barrel near the installation port. The installation pipe is connected to the installation port. An installation block is connected to the terminal of the electric heating rod.

[0014] Furthermore, a hand-tightening block is fixedly connected to the end of the mounting block away from the electric heating rod, and the outer side of the hand-tightening block is provided with several anti-slip stripes.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This aluminum-air battery anode aluminum plate forming device uses an electric heating rod to transfer heat to the outer heat-conducting component through a heat-conducting pipe. The heat-conducting component further increases the amount of metal powder at the powder outlet of the powder outlet, greatly improving the preheating effect of the metal powder.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 4 A device for forming an anode aluminum plate for an aluminum-air battery includes a powder outlet barrel 1. A heat-conducting pipe 2 is connected to the powder outlet at the bottom of the powder outlet barrel 1. The two ends of the heat-conducting pipe 2 are respectively connected to the two ends of the bottom opening of the powder outlet barrel 1. An installation port 101 is provided through one end of the powder outlet at the bottom of the powder outlet barrel 1. An electric heating rod 3 is connected to the installation port 101. After passing through the installation port 101, the electric heating rod 3 is inserted directly into the heat-conducting pipe 2. A heat-conducting component is connected to the outer wall of the heat-conducting pipe 2.

[0020] like Figures 1 to 4 As shown, the aluminum anode plate forming device for aluminum-air batteries in this utility model is structurally similar to existing aluminum anode plate forming devices for aluminum-air batteries, such as the preheating powder supply device for SLM metal 3D printing equipment disclosed in patent publication number CN222710819U. The main improvement of this utility model lies in further improving the preheating effect of the metal powder, such as... Figures 1 to 4 As shown, in the aluminum-air battery anode aluminum plate forming device of this utility model, when in use, the electric heating rod 3 is inserted into the heat conduction pipe 2 through the installation port 101. The heat conduction pipe 2 is heated by the electric heating rod 3, and the high temperature is transferred to the heat conduction component. When the metal powder in the powder discharge barrel 1 falls from the powder discharge port at the bottom, it will fall and move from both sides of the heat conduction pipe 2. At this time, the heat conduction component can increase the contact area between the preheating structure and the metal powder, thereby reducing the leakage of metal powder preheating and improving the uniformity and preheating effect of metal powder discharge preheating.

[0021] like Figures 1 to 4 As shown, the heat-conducting component includes several heat-conducting pillars 4, all of which are fixed to the outside of the heat-conducting pipe 2, and are arranged in an equidistant, staggered pattern on the outside of the heat-conducting pipe 2. Through the multiple equidistant, staggered heat-conducting pillars 4, the metal powder can be diverted by multiple heat-conducting pillars 4 during its descent, thereby allowing more metal powder to directly contact the heat-conducting pillars 4 and the heat-conducting pipe 2, improving the preheating effect of the metal powder.

[0022] like Figures 1 to 4 As shown, the end of the heat pipe 2 furthest from the electric heating rod 3 is connected to a rotary drive motor 5. The rotary drive motor 5 is fixedly installed on the outer wall of the powder outlet at the bottom of the powder outlet barrel 1, and the output shaft of the rotary drive motor 5 passes through the powder outlet barrel 1 and is connected to the end of the heat pipe 2. The end of the heat pipe 2 furthest from the rotary drive motor 5 is rotatably connected to the mounting port 101. During powder dispensing, the rotary drive motor 5 can be started to drive the heat pipe 2 to rotate inside the powder outlet of the powder outlet barrel 1, so that the multiple heat-conducting columns 4 on the outside of the heat pipe 2 can circulate and heat the falling metal powder, avoiding the inability of some heat-conducting columns 4 to transfer heat in time, and further improving the preheating effect of the metal powder. At the same time, the rotating heat pipe 2 and the heat-conducting columns 4 can form a stirring effect at the powder outlet at the bottom of the powder outlet barrel 1, making the powder dispensing smoother and preventing the metal powder from accumulating at the powder outlet.

[0023] like Figures 1 to 4 As shown, a heat insulation block 6 is fixedly connected to one end of the heat pipe 2 near the rotary drive motor 5. The output shaft of the rotary drive motor 5 passes through the powder outlet hopper 1 and is fixedly connected to the heat insulation block 6. A heat insulation pipe 7 is fixedly connected and connected to the other end of the heat pipe 2 away from the rotary drive motor 5. The other end of the heat insulation pipe 7 away from the heat pipe 2 is rotatably connected to the mounting port 101. The heat insulation block 6 and the heat insulation pipe 7 are respectively set at both ends of the heat pipe 2, which can prevent the high temperature of the heat pipe 2 from being transferred to the rotary drive motor 5 and the powder outlet hopper 1, avoiding high temperature from causing failure of the rotary drive motor 5, and reducing heat loss. The heat insulation block 6 and the heat insulation pipe 7 can be made of ceramic or other materials with low thermal conductivity, and need to have a certain structural strength to avoid deformation or breakage during rotation, which would affect the preheating operation of the metal powder.

[0024] like Figures 1 to 4 As shown, an auxiliary bearing 8 is embedded inside the mounting port 101. The inner wall of the inner ring of the auxiliary bearing 8 is fixedly connected to the outer wall of the end of the heat insulation pipe 7 away from the heat conduction pipe 2. When the rotary drive motor 5 drives the heat conduction pipe 2 to rotate, the other end of the heat conduction pipe 2 can rotate more smoothly in the mounting port 101 through the auxiliary bearing 8. It should be noted that the heat insulation block 6 and the auxiliary bearing 8 are sealed with the powder discharge barrel 1 to prevent leakage of metal powder.

[0025] like Figures 1 to 4 As shown, an installation tube 9 is fixedly connected to the outer wall of the powder dispensing barrel 1 near the installation port 101. The installation tube 9 communicates with the installation port 101. The wiring terminal of the electric heating rod 3 is connected to an installation block 10. The electric heating rod 3 passes through the installation tube 9 and the heat insulation tube 7 in sequence and is then inserted into the heat conducting tube 2. The installation block 10 is threadedly fixed to the inside of the installation tube 9. After the electric heating rod 3 is inserted into the heat conducting tube 2 from the installation port 101, it can be screwed into the installation tube 9 through the thread of the installation block 10, thereby fixing the electric heating rod 3 inside the heat conducting tube 2.

[0026] like Figures 1 to 4 As shown, a heat insulation rod 11 is fixedly connected to one end of the electric heating rod 3 near the mounting block 10, and the other end of the heat insulation rod 11 is fixedly connected to the mounting block 10. The power-on terminal of the electric heating rod 3 is connected to the mounting block 10 through the heat insulation rod 11, which can prevent the high temperature of the electric heating rod 3 from being transferred to the mounting block 10, improve the performance of the electric heating rod 3, and reduce heat loss.

[0027] like Figures 1 to 4 As shown, a hand-tightening block 12 is fixedly connected to the end of the mounting block 10 away from the electric heating rod 3. Several anti-slip stripes 13 are provided on the outer side of the hand-tightening block 12. By turning the hand-tightening block 12, the mounting block 10 can be screwed into the mounting tube 9 more conveniently, and the anti-slip stripes 13 can improve the stability of the screwing operation.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
